Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple light sources are connected to multiple connection destinations (power supply and information processor), then the light source device can function properly, but the wiring structure becomes complicated and assembly becomes difficult
Solution Approach 1:
The patent combines multiple wire layers (power supply wires and signal wires) into a single integrated flexible wire board structure. This merging of previously separate wiring paths into one unified board reduces the overall wiring structure complexity while maintaining all necessary connections between light sources, power supply, and information processor.
Solution Approach 2:
The patent utilizes the thickness direction (z-axis) by arranging power supply wires and signal wires in different wire layers stacked vertically. This dimensional arrangement allows multiple wiring paths to coexist without lateral interference, simplifying the two-dimensional layout complexity on the wire board surface.
2Device complexity
If power supply wires and signal wires are arranged in the same wire layer, then the wire board structure is simpler, but wiring interference and assembly difficulty increase
Solution Approach 1:
The patent resolves wiring interference by stacking power supply wires and signal wires in different wire layers along the thickness direction. This vertical separation in the third dimension eliminates lateral interference between power and signal paths while keeping the overall wire board structure integrated and manageable.
3Ease of operation
If a unified wire board is used to connect multiple light sources to power supply and information processor, then assembly ease is improved, but the wire board structure becomes more complex
Solution Approach 1:
The patent segments the wire board into multiple distinct wire layers, with each layer dedicated to specific wiring functions (power supply wires in one layer, signal wires in another). This segmentation organizes the complex wiring into manageable, functionally-separated layers, reducing structural complexity while maintaining assembly ease.
Solution Approach 2:
The patent uses the thickness direction to organize different wire types into separate layers, creating a vertically-stratified structure. This dimensional organization allows the unified wire board to handle multiple connection functions without requiring complex lateral routing, thereby simplifying the overall structure despite the unified design.
